To all lwhom it may concern:

Be it known that I, PETER Coorn Hnwrrr, a. citizen of the UnitedStates, and resident `of Ringwood Manor, county of Passaic, State of New Jersey, have invented certain new and vuseful Improvements in- Vapor` Electric Apparatus, of which the following is a specification.

In United States latentNo. 1,069,695, 1ssued August 12th, 1913, I have shown, de-

1, scribed and claimed a vapor electrlc apparatus having a plurality-of negative electrodes,

and a connnon positive electrode incombination with work circuits connected to one or more of thenegative electrodes. In the same application I also show and describe a vapor electric apparatushavin a plurality of positive electrodesand wor circuits connected therewith. The present application relates more particularly to the latter form or ernbodiment of my invention. Y

The invention is illustrated-in the drawing which is a diagram of a vapor Aelectric rectifier apparatus in combination with circuits in which such a rectifier may be made useful.

Referring to the drawing, I show a'rectifier, 1, containing two positive electrodes 4 :ind 4b and two negative electrodes numbered Q and 3. Work circuits 13a and 14#l ma be connected upv in the circuits of the posltiveelectrodes et and 4b, as shown in the drawing. An apparatus of this sort is found t0 be operative and useful for systems of distribution such as those illustrated, and it has the advantage of furnishing a sin le rectifier apparatus in place of a' plura ity of such devices.

The electrodes 4** and 1P may be of iron, graphite, or other suitable material, and the electrodes 2 and 3 may be of any volatilizahle conducting liquid suitable to the purposes of this invention. Platinum points 5 and 6 are shown projecting above thesurface of the electrodes 2 and 3 respectively, the same being typical of devicefwhich may he used in connection with mercury or other electrodes for forming an -pward. meniscus whereby the entrance o1 .ne current into the negative electrodes is facilitated; localized, and regulated.

A conductor 8 leading from a suitable electric' generator 7 is connected by lead wires 9, 9, with the positive electrodes 4* and 1b through. work circuits 13a and 14. From the other side of the rectifier extend lead wires, 11 and`12, to a return conductor, 10, leading to the generator. The work cir`- cuits may contain translatin devices, 15, 15, and 16, 16, of an'y'suitable c aracter.

Many uses for there'ctifying apparatus might be devised and the present invention relates to only one of a variety of applications which could be made of the broad principle ofthe invention. AS already stated, the utilization of the apparatus as a lamp instead of a rectifier is not excluded from the scope of this invention.

I claim as my inventiva:

1,. A vapor electric appara-tus having a plurality of positive electrodes, and a neg.-

ti electrode, in combination with a sepa' ra tive electrode.

2. A `vapor electric apparatus having 'a plurality of positive electrodes, and a negative electrode, incoinbination with a generator supplying current to the apparatus, one pole of such generator being connected to the negative electrode and the other pole thereof being connected in multiple to several positive electrodes: y

3. A .vapor electric apparatus having a plurality of positive electrodes, and a negative electrode, in combination with a generator supplying current to the apparatus, one pole of such generator being connected to the negative electrode and the other pole thereof being connected in multiple to sev- Aeral positive electrodes through separate Work circuits.
